Now blend up the cauliflower mixture. You can use an emersion blender and blend everything together directly in the pot, or you can use a standing blender and blend the cauliflower and cooking liquid in batches, being careful not to fill the blender too high so the hot liquid doesn't explode out the top. Add the nutritional yeast, white miso paste, and salt and blend to combine.

If you find your sauce is too thin, return the sauce to the pan and cook it down a bit more stirring often so it doesn't burn. If it is too thick, add a bit more vegetable broth or water.

The ways to use this sauce are endless. Toss with pasta, mix into a casserole, top on pizza, make creamy scalloped potatoes, drizzle over baked potatoes, use in lasagna, you name it!
